I referred to this as 'chassis wide uRPF'. I'm not sure if that is big issue in many networks. You run uRPF/strict to single homed customer and uRPF/loose to transit/peering. Often networks already have dedicated peering boxes. I'm not sure, but I believe technically PXF (ES20, SIP600) and EZchip (ES+) should have no trouble doing uRPF, so I think it's just software development issue, that even with these cards, you're bound to this limitation. >From my point of view, as long you can live with LAN cards in 7600 is has excellent bang for buck, with really no competing products out there. But the moment you need to terminate multiple customers to single port and provide QoS (which implies H-QoS) the box has several attractive competitors, most of them are even newer generation, such as MX. -- ++ytti
